Assign Multiple IP Addresses to Windows 8 Computer

What Is Multiple IP Address Assignment

Multiple IP address assignment in a computer means that a network interface card (NIC) of a computer is assigned with more than one IP addresses. Generally, administrators assign only one IP address to an NIC, and if multiple IP addresses are to be assigned, additional NICs are installed on the computer. Assigning multiple IP addresses to a computer allows the computer to communicate with multiple networks in an organization at the same time.

Benefit of Assigning Multiple IP Addresses

Administrators of Windows 8 computer can assign multiple IP addresses to a single NIC in order to eliminate the requirement of installing additional physical NICs. This is a positive step that administrators take in order to let the computer communicate with two different networks in the organization at the same time, and that too without investing funds in purchasing additional LAN cards.

Disadvantages of Assigning Multiple IP Addresses

Because multiple IP addresses are assigned to a single NIC to allow the computer communicate with multiple networks at the same time, any communication that takes place in either or all networks that also requires involvement of the target computer, the single NIC that has been assigned with multiple IP addresses receives heavy amount of network traffic. Because of this, the computer might face network congestion, which might reduce the network speed. This type of network congestion is technically called ‘Bottlenecks’.

How to Overcome Bottleneck Situations?

Although most administrators install multiple NICs to avoid bottleneck situations, in case additional NICs are not available, administrators can install a single NIC with high bandwidth support to reduce the chances of bottlenecks.

For example, LAN card with 100 Mbps support can be replaced with 1 Gbps (1GbE) NIC to remarkably reduce the network congestion issues (bottlenecks).

How to Assign Multiple IP Addresses to a Single NIC?

To assign multiple IP addresses to a single network interface card (NIC) in Windows 8, steps below must be followed:

  1. Use the credentials of administrator account to log on to Windows 8 computer, to which multiple IP addresses are to be assigned.
  2. Click Desktop tile from the Start screen to go to the desktop window.
  3. Once on the desktop window, hover mouse to the bottom right corner of the screen.
  4. From the displayed options in the right, click Settings.

    Click Network and Sharing Center

  8. On Network and Sharing Center window, from the left pane, click Change adapter settings.

    Click Change Adapter Settings

  9. On the Network Connections window right-click the network interface card (NIC), on which multiple IP addresses are to be assigned.
  10. From the context menu that appears, click Properties.
  11. On network adapter’s properties box, double-click Internet Protocol Version 4 (TCP/IPv4) from This connection uses the following items list.
  12. From the bottom of Internet Protocol Version 4 (TCP/IPv4) Properties box, click Advanced button.

  14. Once on the selected tab, click Add button under IP addresses section.

    Click Add Button

  15. On TCP/IP Address box, type the IP address and its corresponding subnet mask in the IP address and Subnet mask fields respectively.

    Specify IP Address and Subnet Mask

  16. Click Add button to add the IP address to the LAN card.
  17. Back on Advanced TCP/IP Settings box, click OK.
  18. Back on Internet Protocol Version 4 (TCP/IPv4) Properties box, click OK to save the changes.
  19. Close all the opened boxes and windows when done.
